NAME

amr -- MegaRAID SCSI/ATA/SATA RAID driver

SYNOPSIS

To compile this driver into the kernel, place the following lines in your
kernel configuration file:
devicepcidevicescbusdeviceamr
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
amr_load="YES"

DESCRIPTION

The amr driver provides support for LSI Logic MegaRAID SCSI, ATA and SATA
RAID controllers and legacy American Megatrends MegaRAID SCSI RAID
controllers, including models relabeled and sold by Dell and Hewlett-
Packard.
LSI MegaRAID SAS controllers are supported by mfi(4) and will not work
with this driver.

DIAGNOSTICS

Driverinitialisation/shutdownphaseamr%d:memorywindownotavailableamr%d:I/Owindownotavailable
The PCI BIOS did not allocate resources necessary for the correct
operation of the controller. The driver cannot attach to this
controller.
amr%d:busmasterbitnotset,enabling
The PCI BIOS did not enable busmaster DMA, which is required for the
correct operation of the controller. The driver has enabled this bit and
initialisation will proceed.

A resource allocation error occurred while initialising the driver;
initialisation has failed and the driver will not attach to this
controller.
amr%d:can'tobtainconfigurationdatafromcontrolleramr%d:can'tobtainproductdatafromcontroller
The driver was unable to obtain vital configuration data from the
controller. Initialisation has failed and the driver will not attach to
this controller.
amr%d:can'testablishconfigurationhookamr%d:can'tscancontrollerfordrives
The scan for logical drives managed by the controller failed. No drives
will be attached.
amr%d:device_add_childfailedamr%d:bus_generic_attachreturned%d
Creation of the logical drive instances failed; attachment of one or more
logical drives may have been aborted.
amr%d:flushingcache...
The controller cache is being flushed prior to shutdown or detach.
Operationaldiagnosticsamr%d:I/Obeyondendofunit(%u,%d>%u)
A partitioning error or disk corruption has caused an I/O request beyond
the end of the logical drive. This may also occur if FlexRAID Virtual
Sizing is enabled and an I/O operation is attempted on a portion of the
virtual drive beyond the actual capacity available.
amr%d:polledcommandtimeout
An initialisation command timed out. The initialisation process may fail
as a result.
amr%d:badslot%dcompleted
The controller reported completion of a command that the driver did not
issue. This may result in data corruption, and suggests a hardware or
firmware problem with the system or controller.
amr%d:I/Oerror-%x
An I/O error has occurred.
